I just bought the last issue of PlancheMag. It is a test issue. In the slalom board test, iSonic 101 was declared "coup de coeur" by the test team, meaning it is one of their favourite boards based on the feelings one gets on the water.
From the very little French I can understand, it seems that the strongest point of the iSonic 101 is the ability to keep high speeds through a variety of changing conditions, being well controllable in gusts and not slowing down in holes; while displaying absolute performances on a par with the best competitors.
